Description

Access control system using smart tagging and biometrics {OMITTED}

The present invention relates to an access control system using smart tagging and biometrics, and in particular, it is possible to confirm the identity of a visitor and manage access by using non-contact smart tagging, and it can be linked with other facilities of a building such as an elevator. It's about a system that exists.

In general, there are card contact and non-contact type card readers. In the case of card contact type, a magnetic card, such as a credit card or cash withdrawal card, is brought into contact with a card reader to read magnetic information. There is a card reading information using an optical signal or a frequency signal, such as a barcode or RFID card.

A non-contact type identification card system is composed of an ID card that transmits identification information as a high-frequency radio signal, and an identification device that receives a signal transmitted from the ID card to confirm a user's identity.

A non-contact identification card system using RFID is widely adopted because of the convenience of enabling the user's identity to be confirmed even if the user does not have to take out the ID card directly and put it in his/her pocket.

Recently, unmanned access control systems have been installed not only in places requiring security, including research laboratories of companies and institutions, but also in apartment complexes, preventing entry without an ID card for identification.

An access management device using a general non-contact identification card system includes an RFID reader that receives RF data, which is user identification information wirelessly transmitted from an ID card, and analyzes the RF data input from the RFID reader to determine whether or not the person is permitted to enter or not. It is composed of a central processing unit that detects, a door lock control unit that controls the locking or opening of the electric door lock under the control of the central processing unit, and an electric door lock that locks or opens the door under the control of the door lock control unit.

With the above configuration, the access control device receives RF data transmitted from the ID card and analyzes it to determine whether or not to allow access to the person, and controls the electric door lock to open the door in the case of an authorized person.

However, the conventional access management device operates only limitedly to access control, does not interlock with other facilities of the building, and has the inconvenience of having to bring the ID card close to the RFID reader for user identification. has problems in meeting the various needs of residents, such as purchasing goods and making emergency calls.

Therefore, the first technical problem to be achieved by the present invention is smart tagging that can improve convenience and portability in the process of entering and exiting and operate facilities or devices of a building in preparation for operations predicted according to the entry and exit of residents. And to provide an access control system using biometrics.

In order to achieve the above second technical problem, the present invention, when the second sensing unit installed inside the front door of the building detects the user's approach using IR detection, sends an approach detection signal to the second RFID recognizer installed in a location close to the elevator door. transmitting; receiving unique information transmitted by smart tagging of the user when the second RFID recognizer receives the proximity detection signal from the second sensing unit; receiving, by the elevator control device, the unique information from the second RFID recognizer, and searching for the unique information in a resident DB to confirm the number of the user's residence floor; and calling the elevator to the floor where the second RFID recognizer is installed by the elevator control device, and setting the target floor number of the elevator to the confirmed number of residence floors.

According to the present invention, there is no need to bring the building access card close to the RFID reader, and home automation can be realized by interlocking the building access with the operation of other facilities or devices in the building, and with only one smart tagging, it is possible to It can satisfy various needs of residents, such as purchase of goods and emergency calls, and thus has the effect of improving the portability of access means.

The present invention provides a system and method that can conveniently unlock the front door, household entrance, etc. using wireless recognition tagging, and automatically inputs the floor number of a resident when a resident with wireless recognition tagging approaches an elevator. to provide.

Hereinafter, the configuration and effects of the present invention will be described with reference to the drawings and preferred embodiments of the present invention. However, the embodiments of the present invention exemplified below may be modified in many different forms, and the scope of the present invention is not limited to the embodiments described below.

1 is a block diagram of an access control system using smart tagging and biometrics according to an embodiment of the present invention.

The smart tagging 100 embeds an RFID tag that stores user's unique information. Hereinafter, smart tagging 100 refers to an access card or stick that a user possesses to enter and exit a building. The access management system according to the present invention is configured to automatically unlock the door when a user with wireless recognition tagging approaches the front door of a building or the front door of each household. Smart tagging 100 according to the present invention may include a plurality of buttons. The smart tagging 100 may be configured to, for example, embed a door open button, drive wireless recognition tagging using a built-in power source when the door open button is input, and transmit unique information wirelessly. The smart tagging 100, for example, embeds an emergency button, and when the emergency button is input, uses a built-in power source to drive wireless recognition tagging, and wirelessly transmits unique information and an emergency call signal to a plurality of RFID recognizers installed in a building. It can be configured to transmit to any one recognizer. The plurality of RFID recognizers include a first RFID recognizer 120 and a second RFID recognizer 140 . Here, a plurality of RFID recognizers are installed in each zone or part of a building to read stored information from smart tagging in which an emergency button is input. A plurality of RFID recognizers may be installed at regular intervals, such as, for example, an underground parking lot of a building, a stairway of a building, or a passage of a building. The plurality of RFID recognizers transmit their own recognizer IDs and unique information to the manager terminal 190 when unique information and an emergency call signal are received.

Wireless recognition tagging is generally a method that does not have a central processing unit (CPU) or a device that can perform simple calculations with a small storage space by embedding a smart card or the like. In particular, wireless recognition tagging is divided into a passive type and an active type. The passive type does not have its own power source and uses the electromagnetic waves emitted from the RFID reader as a power source. It is low-cost tagging. The active type has its own power source and is expensive. . Radio recognition tagging used in the present invention uses an active type.

The first sensing unit 110 is installed outside the front door and outputs an approach detection signal when detecting a user's approach using IR detection.

The first RFID recognizer 120 is installed at a location close to the front door 127 and receives unique information transmitted by the smart tagging 100 when receiving an approach detection signal from the first sensing unit 110. In addition, the first RFID recognizer 120 searches the resident DB for unique information and transmits a door open signal to the door control unit 125 if the user is a resident of the building. Preferably, when receiving an approach detection signal from the first sensing unit 110, the first RFID recognizer 120 is configured to transmit an RF signal to the smart tagging 100 through a directional antenna installed inside or outside the front door. It can be. A directional antenna refers to an antenna designed to radiate strong radio waves in a specific direction or to receive radio waves coming from a specific direction with a particularly high reception rate. In this case, the smart tagging 100 wirelessly transmits unique information corresponding to the RF signal transmitted by the second RFID recognizer 140 . Here, the installation center of the directional antenna is set to be an area outside the front door 127 where the user is normally expected to be located.

The door control unit 125 opens the front door 127 by controlling an operation of a motor connected to the front door 127 according to a door opening signal. Conversely, the door control unit 125 closes the front door 127 by controlling the operation of the motor connected to the front door 127 according to the door closing signal.

The second sensing unit 130 is installed inside the front door of the building and outputs an approach detection signal when detecting a user's approach using IR detection. Preferably, the second sensing unit 130 may be configured to transmit a door close signal to the door control unit 125 when a user's approach is detected using IR detection. In this case, the door control unit 125 closes the front door 127 by controlling the motor operation connected to the front door 127 according to the door closing signal.

The above-described first sensing unit 110 and second sensing unit 130 reduce power waste of the first RFID recognizer 120 and the second RFID recognizer 140, and activate the smart tagging 100 only when a user is in close proximity. It is a means for reading stored information.

The second RFID reader 140 is installed in a position close to the elevator door 147. When the second RFID recognizer 140 receives an approach detection signal from the second sensing unit 130, it receives unique information transmitted by the smart tagging 100.

Preferably, when receiving an approach detection signal from the second sensing unit 130, the second RFID recognizer 140 transmits an RF signal to the smart tagging 100 through a directional antenna installed in a location close to the elevator door 147. It can be configured to transmit. Here, the installation center of the directional antenna is set to be an area in front of the elevator door 147 where a user is expected to be normally located. In this case, the smart tagging 100 wirelessly transmits unique information corresponding to the RF signal transmitted by the second RFID recognizer 140 .

The elevator control device 145 is connected to a dynamometer of the elevator 149 and controls overall operation of the elevator 149 . The elevator control device 145 receives unique information from the second RFID recognizer 140 and searches for the unique information in the resident DB to check the number of the user's residence floor. In addition, the elevator control device 145 calls the elevator 149 to the floor where the second RFID recognizer 140 is installed, that is, the floor where the user is located, and sets the target floor number of the elevator 149 to the confirmed number of residence floors.

The manager terminal 190 displays the location and identity of the user on the screen when making an emergency call using the smart tagging 100 . When the manager terminal 190 receives a recognizer ID and unique information from one of the plurality of RFID recognizers, it displays an emergency call message on the screen of the terminal. In this case, the manager terminal 190 estimates the user's location according to the received recognizer ID, confirms the user's identity according to the received unique information, and displays it on the screen. Accordingly, the administrator can respond to an emergency or emergency situation by dispatching to the location displayed on the screen.

2 is a flowchart of an access management method using smart tagging according to an embodiment of the present invention.

First, when there is no user access, it is determined whether the door open button of the smart tagging 100 is input (Step 205).

At this time, when the door open button of the smart tagging 100 is input, even if there is no user access, the unique information transmitted from the smart tagging 100 is received by the first RFID recognizer 120, and the received unique information It is searched in the resident DB (process 220) and it is determined whether the user is a resident (process 230).

Meanwhile, when the door open button of smart tagging is not input and the user approaches the first sensing unit 110 (process 210), the unique information sent from the smart tagging 100 is sent to the first RFID recognizer 120. received, and the received unique information is searched in the resident DB (step 220) to determine whether the user is a resident (step 230).

On the other hand, if the user does not approach the first sensing unit 110 (step 210), the process of determining whether the door open button of the smart tagging 100 is input (step 205) is returned.

When the first RFID recognizer 120 confirms that the holder of smart tagging is a resident in the resident confirmation process (step 230), the door control unit 125 opens the front door by using a motor operation (step 240).

When the user passes through the front door, the second sensing unit 130 installed inside the front door of the building determines whether the user's approach is detected using IR detection (step 250). At this time, if the user's approach is not detected, a standby state is maintained in which the above process (process 250) is continuously repeated.

When the user's approach is detected, an approach detection signal is transmitted to the second RFID recognizer 140 installed in a location close to the elevator door 147, and the second RFID recognizer 140 sends the user's smart tagging 100 The unique information is received and transmitted to the elevator control device 145, and the elevator control device 145 searches the received unique information in the resident DB and confirms the number of the user's residence floor (step 260).

Finally, the elevator control device 145 calls the elevator to the floor where the second RFID recognizer 140 is installed, and sets the target floor number of the elevator to the confirmed residence floor number (step 270).

Accordingly, a resident of a building with smart tagging automatically calls an elevator to the current floor through the front door without a separate button operation, and a resident with smart tagging in a buffer or memory that stores the target floor of the elevator. The number of the floor where the person resides can be entered automatically.

Such an algorithm can be applied not only to the front door, but also to the front door of each household and to the elevator close to the front door of each household. When such an algorithm is applied to the front door of each household, unlocking the door of each household by smart tagging can be interlocked with a home network, a security device, and the like. In addition, as described above, an emergency call function can be performed using smart tagging and a pre-installed RFID recognizer, and when electronic money information is stored in smart tagging, it is configured to enable small-amount payments in shopping malls in buildings. can do.
